"While the FBI does not comment on operational specifics, the FBI and Gila River PD are conducting interviews, gathering evidence, sharing information, and collectively working to identify all angles of the investigation. There is a widely variable pace to investigations given the need for methodical and thorough evidence-gathering," the FBI said, according to the outlet.
A "charging decision" for the two suspects will be made once that investigation is complete, the agency said.

Briese was still in training, and had been with the department for less than a year, Fox News Digital previously reported.
In a Facebook post, the Gila River Police Department said that the incident involved a large crowd of people, and that multiple gunshots were fired.

"I know I speak for our entire community when I say that we grieve for our fallen and injured police officers and every community member touched by such tragic violence," Gila River Indian Community Gov. Stephen Roe Lewis said in a statement. "Nothing cuts deeper than a life cut short."
GRPD could not immediately be reached for comment.
